Answer: Observational ; does not
Step-by-step explanation: The main distinguishing factor between an experimental study and an observational study lies in the administration of treatment to the participant of the study. In experimental study, some or all the participant in the study are subjected or exposed to a certain treatment and their response to such treatment. ON THE OTHER HAND, Observational study is usually employed when there is a need to gather information on a particular subject matter without directly influencing the participants. In the scenario above, participants were not given any TREATMENT as they were only required to gather information and not to measure the effect of a treatment.
Hello there,
First off what is scientific notation?
Scientific Notation is<span> the way that scientist handle very large or very small numbers..
</span>for example, instead of writing 0.0000000056 we write 5.6x10 (exponent -9)
So, now we got that out the way lets look up here at the choices....
I would say that 7.8x10 (exponent -5) would be the answer! :)
I hoped this helped!!!! :)))
God bless you.
Answer:
225
Step-by-step explanation:
